The Six Models of AbnormalityAbnormal PsychologyJuly 2, 2017Professor Vareene-ThomasThe Six Models of AbnormalityIn the middle ages, if a person had unusual thoughts or acted an unusual way clinical scientists would typically agree on a single model of abnormality which would bebased on the beliefs of their culture. The scientists would often assume that the devil was the cause of this abnormal thought and their treatments would include prayers and whippings to drive the foreign spirits from the body (Comer, 2014). Today, there are six different models of abnormality psychologists use to treat a patients abnormal functioning. One of which is the biological model. The biological model, also known as the medical model, believes that the key to human behavior is physical process. Abnormal behavior, emotions and thinking are caused by biological dysfunctions such as certain hormone levels increasing, genetics, faulty genes, certain neurons in the brain dysfunctioning, infections or changes in neurotransmitters (Devshi, 2014). Anatomy plays a large role in certain disorder. Each part of the brain plays a specific role in how a person functions. For example, the amygdala has a key role in emotional memory and thehippocampus is in charge of regulating memories and emotion (Comer, 2014). Researches have found connections between certain disorders and specific areas of the brain. An example would be Huntington’s disease. The textbookAbnormal Psychology states, “Huntington’s disease is a disorder marked by violent emotional outbursts, memory loss, suicidal thinking, involuntary body movements, and absurd beliefs.

Neurotransmitters play a key role in delivering messages of “firing” or “inhibiting” through the brain. Certain mental disorders are caused by neurotransmitters acting abnormally (Comer, 2014). Depression is one of these disorders. Depression is caused by low activity of serotonin and dopamine. Once psychologists have examined thepatient, they can decide which biological treatment would be best for the patient. There are three leading biological treatments: drug therapy, electroconvulsive therapy and psychosurgery. Drug therapy is the most common of the three. Drug therapy uses four major psychotropic drug groups: antianxiety (helps reduce anxiety and tension), antidepressant (helps to improve mood in depressed people), antibipolar (helps steady moods of people with bipolar disorder) and antipsychotic (helps decrease hallucination, psychotic disorders and confusion). Electroconvulsive therapy is where two electrodes are attached to the patient’s forehead and sends electrical volts through the brain. This treatment helps patients to feel less depressed. Psychosurgery is a type of surgery for mental disorders and is used as a last resort if no other treatments have worked (Comer, 2014). The second model of abnormality is the psychodynamic model.
